[0002] When the existing 900×1200 bottom-mounted jaw crusher is used to crush aluminum anode carbon blocks, the following two situations always occur: First, due to the large size of the entire carbon block, with a length, width and height greater than 1700×650×600mm, the carbon block can only enter 1 / 3 to 1 / 2 of the crushing chamber, the meshing surface is small, and the carbon block is slippery, especially when it is a raw block, the surface contains asphalt components, so when crushing, the carbon block slips and moves up between the moving and fixed jaw plates, making it difficult to break. Sometimes it cannot be broken for a long time, and even needs to be taken out manually, and it cannot be broken, and the crushing efficiency is extremely low; Second, after the movable and fixed jaw plates of the crusher have been used for a period of time, the jaw plate teeth are worn very brightly by the carbon block, the meshing force is greatly reduced, the carbon block is not easy to break, the crushing time is extended, the jaw plate replacement cycle is short, and the maintenance cost increases.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 , Figure 2 The utility model provides a technical solution: a crusher for anode carbon blocks, comprising a frame 1, a fixed jaw plate 2, a movable jaw plate 3, a movable jaw 4 and a driving device 7.

[0024] The fixed jaw plate 2 is arranged on the frame 1. One end of the movable jaw 4 is connected to the frame 1 through an eccentric shaft. The driving device 7 is arranged on the frame 1. The driving end of the driving device 7 is connected to the eccentric shaft. The other end of the movable jaw 4 is connected to the frame 1 through a toggle plate 5. A movable jaw plate 3 is provided on the side of the movable jaw 4 close to the fixed jaw plate 2. A carbon block crushing chamber is formed between the fixed jaw plate 2 and the movable jaw plate 3.

[0025] The fixed jaw plate 2 is provided with a fixed jaw plate crushing surface. The movable jaw plate 3 is provided with a movable jaw plate crushing surface. The fixed jaw plate crushing surface is concave inwardly in a direction away from the movable jaw plate 3. The movable jaw plate crushing surface is in contact with the fixed jaw plate crushing surface. The fixed jaw plate 2 is tilted. The top of the fixed jaw plate 2 is tilted in a direction away from the movable jaw plate 3.

[0026] The fixed jaw crushing surface of the fixed jaw plate 2 and the movable jaw crushing surface of the movable jaw plate 3 are set in a hyperbolic manner. Different from the partial curve setting of the prior art, the utility model adopts the hyperbolic setting of the fixed jaw crushing surface and the movable jaw crushing surface to increase the contact area between the two and improve the crushing effect.

[0027] Furthermore, the driving device 7 is a motor. The driving end of the driving device 7 rotates counterclockwise. Figure 1 Based on the main viewing angle, the driving end of the driving device 7 is Figure 1 The motors in the prior art mostly rotate clockwise, and most of them use servo motors that can be flexibly changed. However, most of the settings in the prior art are upper rubbing type crushing, so the main rotation direction must be clockwise. Because if the motor in the prior art rotates counterclockwise, it will accelerate the fall of the carbon block, resulting in the carbon block not being completely crushed and discharged from the bottom of the carbon block crushing chamber.

[0028] Furthermore, a plurality of fixed jaw plate crushing teeth are provided on the fixed jaw plate crushing surface of the fixed jaw plate 2. A plurality of movable jaw plate crushing teeth are provided on the movable jaw plate crushing surface of the movable jaw plate 3.

[0029] Furthermore, the top of the carbon block crushing chamber formed between the fixed jaw plate 2 and the movable jaw plate 3 is higher than the eccentric shaft. The top of the carbon block crushing chamber between the fixed jaw plate 2 and the movable jaw plate 3 is adjusted from being lower than the top of the movable jaw 4 in the prior art to being higher than the top of the movable jaw 4. And most of the prior art adopts an inclined setting of the movable jaw 4. However, the utility model adopts the movable jaw 4 set perpendicular to the ground. The height of the carbon block crushing chamber is increased, and the crushing meshing angle between the movable jaw 4 and the frame is changed, so that the force on the carbon block is changed from the upward rubbing type to the downward pressing type. It not only avoids the splashing of carbon blocks, but also further improves the crushing effect.

[0030] Furthermore, the driving end of the driving device 7 drives the eccentric shaft through a belt 9 .

[0031] Further, one end of the toggle plate 5 abutting against the movable jaw 4 is higher than the other end of the toggle plate 5. The frame 1 is provided with a tightening device 8 and a pull rod spring device 6. The other end of the toggle plate 5 is connected to the tightening device 8. One end of the pull rod spring device 6 is rotatably connected to the bottom of the movable jaw 4 near the toggle plate 5.

[0032] The utility model is suitable for a 900×1200 carbon block crusher. After testing, when the driving power and the weight of the equipment are not increased, the processing capacity of the utility model is increased from 6-10 blocks per hour in the prior art to 20-30 blocks, providing more than 3 times the efficiency. The service life of the movable jaw plate 3 and the fixed jaw plate 2 is increased from 6 months in the prior art to 12-15 months, and the crushing particle size is reduced from 200-240mm in the prior art to 100-150mm, which greatly improves production efficiency and reduces operating costs.

[0033] Working principle:

[0034] The driving device 7 is turned on. The carbon block is placed from the top of the carbon block crushing chamber. The driving device 7 drives the eccentric shaft to rotate, thereby driving the movable jaw 4 to move. Since the driving device 7 moves counterclockwise and is driven by the belt 9, the eccentric shaft also moves counterclockwise. A downward pressure is generated between the movable jaw 4 and the fixed jaw plate 2. The movable jaw plate 3 and the fixed jaw plate 2 crush the carbon block. The processed carbon block is discharged from the bottom of the carbon block crushing chamber.
